Hey,Scout!ScoutByTelenavGoesHands-FreeWithNewVoiceCommandFeature

Hey, scout! Scout, the popular GPS navigation app developed by Telenav, has just gone hands-free.
Through its latest update, Scout has gained a new feature that allows for hands-free voice commands. In fact, with the arrival of this voice recognition feature, Scout is said to be the first mobile navigation app to support hands-free search and navigation.
Akin to Google's "OK Google" feature, Scout's new feature is activated using a hotword. In Scout's case, it's "Hey Scout!" As explained by Telenav:

Here’s how it works: With Scout running in the foreground, you (or your passenger) simply say, “Hey Scout” to launch the app’s voice recognition search capabilities. After the beep, just say, “Drive Home,” “Drive to Best Buy,” “Find cheap gas,” or “Map of San Francisco.”
